664475 divided by 25 
We want to divide 664475 by 25.

On to step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 25

Step 2:
66 divided by 25 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 50 from 66 and we're left with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 25

Going ahead to step 3:
25 goes into 164 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 150 away from 164, we end up with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 25

On to step 4:
The number 25 fits into 144 5 times, leaving a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Subtracting 125 from 144 leaves us with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 25

Moving on to step 5:
25 goes into 197 7 times with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 2657.0
If we take 175 away from 197, we end up with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 25

Advancing to step 6:
25 goes into 225 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 26579.0
If we take 225 away from 225, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26579.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26579.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 26579.0, and the remainder is 0.0.
